TUBULARLY-STRAPPED FILTER'PLATE OR SHEET.

SPECIFICATION forming part of Letters l atent No. 607,953, dated July 26, 1898.

Application filed December 30, 1897, Serial No. 664,518. (No model.) Patented in Austria March 30, 1895, No. 45/1,99'7;

in Belgium April 4, 1895, No. 114,917; in Hungary April 2 in Russia July 30,1896,No.15.605.

To aZZ whom it may concern:

Be it known that I, KAREL PROKS, a subject of the Emperor of Austria-Hungary, residing at Karlin-Prague, in the Kingdom of 5 Bohemia, Austria- I-Iungary, have invented certain new and useful Improvements in Tubularly-Strapped Plates or Sheets, (patented in Austria March 30, 1895, No. 45/1,!)97; in

Hungary April 23, 1895, No. 2,650; in France May 4, 1895, No. 247,144; in Belgium April 4, 1895, No. 114,917,. and in Russia July 30, Russian time, 1896, No.15,605;) andI declare the following to be a full, clear, and exact description of the same.

The usual perforated plates or sheets are not rigid enough for certain filtering and other purposes. My improvement consists in applying for such purposes plates of iron, steel, or any other appropriate metal into which annular or other tubes are pressed,

these tubes being composed of parallel strips alternately bent both sides of the plates. Such plates are very rigid, and even if the filtering fabrics are pressed against them by the pressure of the filtered juices very little filtering-surface remains inactive.

My invention relates to tub ularly-strapped plates or sheets with reference to the accompanying drawings, in which- Figures 1 and 2 are a tubularly-strapped plate in a front View and in a transverse section through a: or in Fig. 1. Figs. 3 to 12 are 3,1895,N0. 2,650; in France May 4, 1895, N0- 247,l44, and

difierent Varieties of the tubularly-strapped plate or sheet in transverse sections through y y in Fig. 1.

Similar letters refer to similar parts throughout the several views.

In producing my tubularly-strapped plates or sheets parallel tubes r 0" result in producing parallel strips and bending them alter- 4o nately to one and to the other side of the plate into different shapes. In Fig. 1 a circular shape of the tube is shown, while in Fig.

4 the section of such a tube is flat, in Fig. 5 compressed in the other direction, and so on, the alternate strips being signed 1 2, 3 4, 7 8,

9 10, 11 12, 13 14, 15 16, 17 18, 19 2O 21, and 23 24 25. I do not limit myself to a certain section or to certain shapes of the sections of such perforated tubes, if only they are formed by alternate parallel strips in such plates for the said purpose.

What I claim as my invention, and desire to secure by Letters Patent, is=- A filter-plate having parallel tubes r, r, formed by cutting strips from the plate and bending them alternately in opposite directions, substantially as described.

In witness whereof I have hereunto set in hand in presence of two witnesses.

KAREL PROKS.
